Cookies must go in the HTTP header. If you print HTML first, you've given up your chance to print any HTTP headers. Print the header with any cookies first.

if ($ENV{'REQUEST_METHOD'} eq "POST") {
    read(STDIN, $request,$ENV{'CONTENT_LENGTH'}) or die "Could not get
+ query\n";

}

@parameters = split(/&/,$request);

foreach $p (@parameters){
    $p =~ s/\+/ /g;
    ($para,$value) = split(/=/,$p);
    $para =~ s/%([0-9A-F][0-9A-F])/pack("c",hex($1))/ge;
    $value =~ s/%([0-9A-F][0-9A-F])/pack("c",hex($1))/ge;
    $PAIRS{$para} = $value;
}

Get rid of this code; it's buggy (I count at least three bugs and one denial of service attack) and you're already using CGI. Use its param() functions and save yourself the headache.
